What Is Cloud Computing Explained Simply
Cloud computing is the provision of various services over the Web. that is everything could be provided via the internet.
These services include:
- Data storage
- Servers
- Databases
- Networking
- Software applications
- Artificial Intelligence tools
- Security services
Instead of buying and maintaining costly hardware, cloud computing users rent computing resources from the cloud provider and pay only for the resources that they actually use.
Simple Example
Whereas your personal device would store everything for you, instead it is housed remotely in data centres run by cloud providers.
No matter you‘are storing pictures in Google Drive, accessing Netflix, or signing into Microsoft 365, you are using cloud computing.
Key Benefits
| Benefit | Description |
| Cost Savings | Eliminates expensive hardware purchases |
| Scalability | Resources increase or decrease instantly |
| Accessibility | Access from anywhere with internet |
| Security | Enterprise-grade protection available |
| Reliability | High uptime and disaster recovery |
| Speed | Rapid deployment of applications |
Once you understand the fundamentals, you can explore the broader benefits of cloud computing, including scalability, flexibility, and cost efficiency for organizations of all sizes.
Types of Cloud Computing Models
The characteristics of cloud computing can be classified under three service models. There are:
- Public Cloud
The infrastructure is provided by third parties.
Examples:
- Amazon Web Services (AWS)
- Microsoft Azure
- Google Cloud Platform
Best for:
- Startups
- Small businesses
- Web applications
- Software development
- Private Cloud
Dedicated infrastructure; Infrastructure is dedicated to an organization.
Benefits:
- Greater control
- Enhanced security
- Regulatory compliance
Best for:
- Healthcare organizations
- Government agencies
- Financial institutions
- Hybrid Cloud
Merge public and private clouds.
Benefits:
- Flexibility
- Cost optimization
- Improved workload management
Best for:
- Large enterprises
- Organizations with sensitive data
Beginners exploring online infrastructure often start by comparing leading cloud computing platforms used by businesses worldwide.
Public vs Private vs Hybrid Cloud
Choosing the most appropriate cloud deployment model appears to be the most important choices that a organization can make, as all models have a very profound impact on cost, security, agility and control.
By understanding the existing distinctions between the models, organizations can choose the best infrastructure to address their operational needs, compliance standards and growth strategies.
| Feature | Public Cloud | Private Cloud | Hybrid Cloud |
| Ownership | Third-party provider | Single organization | Combination of both |
| Initial Cost | Low | High | Medium |
| Operating Cost | Pay-as-you-go | Higher ongoing costs | Balanced |
| Security | High | Very High | Very High |
| Scalability | Excellent | Moderate | Excellent |
| Customization | Limited | Extensive | Extensive |
| Compliance Support | Moderate | Excellent | Excellent |
| Deployment Speed | Fastest | Slower | Moderate |
| Maintenance | Provider-managed | Organization-managed | Shared responsibility |
| Best Use Case | Startups & SMBs | Regulated industries | Large enterprises |
Leading Cloud Solutions by Deployment Model
| Cloud Model | Popular Solution | Ideal For | Official Resource |
| Public Cloud | AWS | Scalable applications and startups | AWS Cloud Services |
| Public Cloud | Microsoft Azure | Enterprise workloads | Microsoft Azure Cloud Concepts |
| Public Cloud | Google Cloud | AI and analytics workloads | Google Cloud Overview |
| Private Cloud | VMware Private Cloud | Enterprise infrastructure | VMware Private Cloud Solutions |
| Private Cloud | Red Hat OpenShift | Hybrid and private cloud deployments | Red Hat OpenShift Platform |
| Hybrid Cloud | IBM Hybrid Cloud | Enterprise hybrid environments | IBM Hybrid Cloud Solutions |
| Hybrid Cloud | Oracle Cloud Infrastructure | Enterprise databases and applications | Oracle Hybrid Cloud |
By 2026, most organizations will have adopted hybrid cloud as the long-term IT strategy of choice because it offers both the unlimited scale of pubic clouds to the everything-as-a-service world and, equally, the controls, resilience, cost-savings and security advantages of private infrastructure. However:
- A Public Cloud is still the cheapest solution for startups and developing businesses.
- Privates Cloud continues to be a ideal solution for highly regulated industries.
- Hybrid Cloud is the most well-balanced solution in terms of flexibility, security and performance for large enterprise.
As organizations continue adopting digital technologies, demand for professionals in cloud computing careers continues to grow rapidly.
Cloud Computing for Beginners
If you are new to cloud technology, focus on understanding these core concepts:
Cloud Service Models
SaaS (Software as a Service)
Software is accessed through internet by the users.
Examples:
- Gmail
- Dropbox
- Zoom
PaaS (Platform as a Service)
Developers create apps without managing servers.
Examples:
- Google App Engine
- Azure App Service
IaaS (Infrastructure as a Service)
Offers virtual servers, networking, and storage.
Examples:
